  日期：2007.10

  trans-configuration ((2S,4R)- and (2R,4S)-) were found to be less stable than the corresponding isomers of the cis-configuration ((2R,4R)- and (2S,4S)-) and to undergo epimerization of the C-4 chiral center in the presence of 25% TFA used during Boc deprotection. The synthetic route developed should be applicable to the synthesis of a variety of peptide and amino acid conjugates of 4-aminocyclophosphamide
